SPECIFICATION forming part of Letters Patent N o. 433,626, dated August 5, 1890.

Application filed August 26, 1887. Renewed January 15, 1890. Serial No. 336,972.

To all whom it may concern:

Be it known that I, JOHN lV. JONES, of the city of Utica, in the county of Oneida and State of NewYork, have invented certain new and useful Improvements in Cloth-Board Machines; and Ido hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

My invention relates to an improved machine for the manufacture of cloth-boards; and it consists in the mechanism hereinafter pointed out, described, and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of my machine. Fig. 2 represents a plan view of the same; and Fig. 3 represents a transverse sect-ion of same on line A A, Fig. 1, the parts shown in Fig. 3 Alying to the left hand of line A A, Fig. l. Figs. 4., 6, and 8 represent plan views of the boards produced upon the machine and which are introduced in order to explain the operation of the machine. Fig. 5 represents a transverse section of Fig. 4 on line l5 B. Fig. 7 represents a transverse section of Fig. 6 on line O C. Fig. 9 represents a transverse section of Fig. S on lineD D, and Fig. 10 represents a transverse section of Fig. 8 on line F. E. Fig. 11 represents a front elevation of the saw and a portion of the attached arbor or shaft, and Fig. l2 shows a side elevation of the same. Fig. 13 represents an end elevation of the rotary cutter-I employ, and Fig. 14 represents a side elevation of a portion of the same.

Like figures of reference referto like parts in the several gures presented.

Having described my machine in relation to the drawings, I will now proceed to describe its construction.

I provide a suitable bed or table 1, Figs. 1 and 2, having attached to and projecting downwardly therefrom suitable legs 2, Fig. 1. There are two sets of legs-one on each side of the machine-but one set being shown in the drawings. These legs are braced in (No model.)

any suitable manner, so as to render the machine iirm and stable. In the `construction shown girts 3, Fig. 1, are used to bind or tie the legs together, and in or upon them are formed bearings at, Fig. 1, for the reception and retention of main shaft 5 of the machine. This shaft is free to rotate in its bearings, and powerA for operating the machine is applied to it in any suitable manner. Mounted upon shaft 5 and rigidly connected therewith by keys, set-screws, or any other known method is pulley 6, Fig. 1, which carries the belt that connects it with the other pulleys of the machine.

Mounted upon the bed or top of the table and properly fastened thereto I provide a metallic bed or frame 7, Figs. 1, 2, and 3. This bed or frame carries the various arbors or spindles upon which are mounted the saw, the rotary cutters, and other parts that are hereinafter described, and is constructed substantially as follows: It consists, primarily, of a rectangular bed or frame having upwardly-projecting Walls or fianges 8 on its edges, the inner opposing facesof which are beveled, as shown at 9, Fig. 3. Rigidly attached to the bed at or near its center are the double journal-boxes 10, Figs. 1 and 2, in which is mounted in such manner as to admit vof a free rotation the arbor or shaft 11, which carries the circular saw 12.

Reference to Figs. 1 and 2 will show thatI also provide two other double journal-boxes 13 13. These are gibbed or fitted into and between the beveled walls 9 of the bed in such manner as to prevent their lateral vibration or play and still permit them to move horizontally either to or from the center. This movement is accomplished through the medium of the adjusting-screws 14., Figs. l and 2. These screws are squared at theirouterends, as shown at l5, to admit the use of a wrench for rotating them. The movable journalboxes 13 are each provided with a downwardlyprojecting lug 16, Fig. 1. These lugs are perforated for the reception of screws 14. The ends of screw 14 are reduced in size where they enter lug 16, which forms a shoulder, which opposes one end of the lug. The reduced port-ions of the ends of the screws are IOO sufficiently long to project through the lugs far enough to receive a collar and pin, as shown at 17, Fig. 1. The screws are thusfree to rotate in the lugs, but not to move laterally therein. Projecting upwardly from the bed of the machine, to which they are rigidly attiached, I provide lugs 18, Fig. 1. These are perforated and screw-threaded on their interior to lit the corresponding screw-threads upon adj Listing-screw 14. It will be readily seen that rotation of the adjusting-screws 14 will cause journal-boxes 13 to move either toward or from the center otl the machine, depending upon the direction of the rotation of the adjustment-screws. Journaled in each of t-he movable boxes in such manner as to be free to rotate Vtherein I provide appropriate spindles or arbors for the reception of rotary cutters 19, Figs. l and 2. The right-hand one of these rotary cutters projects from the machine to a linesubstantially flush with the saw, and the left-hand cutter projects to a line substantially flush with the line of the inner face of the saw. The preceding cutter-the one on the right-is intended to cut-the slot44 in the material for the passage of the shaft on which the recessing-saw is mounted, and also for the reception for a spring or elastic, and the succeeding cutter-the one to the left-is intended to enlarge or trim the slot made by the preceding cutter. Mounted upon each of these arbors, together with the central one that carries the saw and rigidly connected therewith, I provide flanged pulleys 20, Figs. 1, 2, and 3. As the plane of movement of the adjustable boxes is tangent to the periphery of pulley 6, it follows that any movement of the adjustable boxes must result in a change in the length of the belt that connects them with pulley 6.

To compensate for the changing lengths of belt required, I provide the following mechanism: Hinged to the bed of the machine by lugs 21 and rod 22, Figs. 1 and 2, I provide the bifurcated curved arm 23, Figs. 1, 2, and 3, having journaled in it in such manner as to freely rotate the flanged pulley 24, Figs. 1,' 2, and 3. The end of arm opposite to the hinge and beyond pulley 24 is contracted and brought together, and the outer end of it formed into a' handle, as shown at 25, Fig. 1. Projecting upwardly from the bed of the machine I provide a curved slotted sword piece or guide 26, Fig. 1. The bifurcated arm contaets with one side of the guide and is connected therewith by the thumb-nut and bolt- 27, Figs. 1 and 2. The arm is perforated for the reception of shank of bolt 27, while the other end projects through the slot in the guide far enough to receive the thumb-nut. The arm can be moved into any desired position and held there by tightening the thumbnut. Belt 28, Fig. 1, partially encircles and enwraps the whole system of pulleys, Consequently any variation in length of belt required, due to the movement of the movable .adj listing-screw 34.

boxes and their attached arbors and pulleys, can be compensated for by varying the location of the arin 23 and its attached pulley 24.

In order to successfully operate my machine, itis necessary to provide some means by which the boards to be operated upon canl be retained in certain definite positions relative to the saw and the rotary cutters. To accomplish this end, I provide the following mechanism: The edge of the bed next to the saw and rotary cutters is recessed, as shown at 29, Fig. 3, to admit of the reception of the slotted uprights 30, Figs.` 1, 2, and 3, and permit their free vertical movement therein. These slotted uprights are tied or bound together near their upper end by the tie or girt 31, Figs. 1 and 3. This tie or girt is adjustable vertically upon the slotted uprights, and is heldin any desired position therein bythe thumb-nuts and bolts 33, Figs. 1 and 2. (Not shown in Fig. 3.) It will be noticed by reference to Fig. 1 that I employa screw 34 for elevating or lowering the L-shaped tie orgirt 32, which acts as a guide for the material fed to the machine or upon which the machine operates. The girt 32 is properly perforated and screw-threaded for the reception of the The upper end of'this screw is reduced in size and inserted into a proper perforation in lug 35, which is attached to and projects from the bed of the machine.

(Not shown in Figs. 2 and The reduced end of screw 34is sufficiently long to project through the lug far enough to receive an ordinary collar and pin, which admits of the rotation of the screw, but does not admit of its vertical movement. at its lower end with a thumb-nut or equivalent device to facilitate its manipulation.

It will be observed that when the L- shaped girt 32 is, by means of the thumb-nut 33, clamped to the uprights 30, rotation of the screw 34 will result in 'either raising or lowering the connected parts, depending upon the direction in which the screw is rotated.

Reference to Figs. 11 and 12 will show the construction of the saw I use in my machine,

and which, so far as I am aware, is new and novel as respects its combination and attachment to and with the arbor or spindle upon which it revolves.

Heretoforc, so far as I have been able to` ascertain, it has been the general custom in attaching a saw to its arbor to superimpose the saw between collars, which, in commonv with the saw, were perforated to admit of the insertion of the arbor. This construction necessitated the use of a nut or equivalent device to tighten the collars and Vclamp the saw between them. Other devices have been in limited use; but none of them', so far as I am informed, have attained the ends sought and accomplished in my invention-viz., av

saw, one side of which is a perfectly plane surface with no projection of any kind thereon. 35, Figs. 11 and 12, shows an ordinary The screw is provided IIO VIf.)

circular saw. ThisI attach to its arbor 36 in such manner that one of the sides of the saw shall be a perfectly plane surface. Various modes of attachment can be utilized. The saw may be perforated and the outer edges ofjthe perforation countersunk, so that the end of the arbor may be riveted down iiush with its surface, or it may be screwed onto the arbor. Various other means would -readily suggest themselves to one skilled in the art. As it is not desirable to remove the saw from its arbor after being once attached thereto, I preferably construct arbor 36 of such form and size that it may be inserted into a proper orifice in the end of the main arbor or spindle of the machine, as shown at 37, Fig. 2, and be held therein by set-screws, ordinary taper lit, or any other known means. A variety of sizes of saws can be kept in stock and 'used as occasion requires.-

The rotary cutters employed by me are represented in Figs. 13v and 14, which are respectively end and side views of the same. They consist, essentially, of a cylinder of steel, havinglateral longitudinal depressions, the edges of which form cutting-edges, as shown at 38, Figs. 13 and 14. The cutters are properly designed and constructed to lit orices in the main arbors of the machine, as shown at 39, Fig. 2, and are held therein by any suitable means. I do not, however,limit myself to the particularstyle or shape of cutter shown, as various other shapes or style could be made to answer the same purpose.

In describing the operation of my machine it will be necessary to refer to Figs. 4, 5, (i, '7, 8, 9, and 10, which show the nature of the operation performed by it. The boards represented in the figures are cut to proper length and their ends rounded, when the bal-` ance of the operations are performed on the machine. Each board is provided with a central longitudinal recess or pocket 40 for the reception of a tag or label 41. This tag or label has connected to it near one end one end of the coiled spring or its equivalent 42. The other end of the coiled spring is connected with the board at 43. The spring lies in the slot` that forms a communication between the central pocket 40 and the outside of the boards. This construction allows the tag 41 to be Withdrawn from the pocket 40, examined, and then automatically retracted into the pocket by the action of the coiled spring. Thefunction of my machine is to cut or form the pockets of the slot described. The boards are set upon their edge upon the L-shaped guide or girt 32, Figs. 1, 2, and 3, and their inner and upper faces held against the girt 31, Figs. 1 and They are then passed from right to left along and across the face of the machine. They rst come in contact wit-h the right-hand rotating cutter 19, which cuts the slot 44, Figs. 8, 9, and l0. The movement of the board being continued it next contacts with circular saw 12, Figs. 1, 2, and 3, which cuts the pocket or recess 40, Figs. 4, 5, 6, 7, 3, 9, and 10. Passing still farther along the board contacts the left-hand rotating cutter 19, which enlarges the slot 44, as shown at 45, Figs. 4, 5, 6, and 7. To limit the longitudinal movement of the board, I employ movable stop 46, Figs. 1 and 2, which can be moved along girt 32 to any desired position and held there by crossheadcd screw 47. For holding the board against the side of the girt I employ flat spring 48, Figs. 1, 2, and 3, which contacts `the sidevofthe board and holds the same firmly against the girt. In the foregoing operations it is assumed that the sau7 and rotarycutters are revolving ata sufficient speed to accomplish the processes described.

Various sizes and combinations of cutters and saw can be employed to produce a great variety of results; hence I do not limit myself to the specific styles` of cutters and products herein described. The spindles carrying the rotary cutters being adjustable laterally, andthe girts and attached parts that form guides for the work while the same is in process being vertically adjustable, it follows that great variety of work can bie produced upon my machine.

Itis obvious that various changes in the structure and conformation of my machine could be made without departure from the spirit or central feature of my invention, which is the employment, in combination with rotary cutters, of a circular saw having one of its sides a perfectly plane surface; hence I do not limit or confine myself to the precise specific construction, combination, and conformation of parts herein set forth and described.
